A SCARCE issue that is not well understood by numismatists. The coin was was thought to have been minted by L. Antonius brother of Marcus Antonius. Later research W. E. Metcalf, SNR 88 (2009), indicates that the coin may be more attributed to L. Sempronius Atratinus, Quaestor. The mint Ionia, Ephesus is also not certain and may be Pergamum or possibly a third mint altogether as the style does not follow the issues of these mints.
Really nice reverse with all nicely defined serpents!
